Restore remote-faule detection, which periodically checks for
remote-fault on the MAC layer. In case physical link appear to be
up but fault is set, it will provide a link down indication, and
when the fault is cleared, it will indicate link up again.

Until now, the bnx2x driver needed at least 2 available msix interrupt
vectors in order to use msix. This patch add the possibility of configuring
msix when only one interrupt vector is available.
Notice this patch contains lines with over 80 characters, as it keeps print
strings in a single line.

In the existing code, we only stop queue when the ringbuffer is full,
so the current packet has to be dropped or retried from upper layer.
This patch stops the tx queue when available ringbuffer is below
the low watermark. So the ringbuffer still has small amount of space
available for the current packet. This will reduce the overhead of
retries on sending.

When a bonding device is configured with fail_over_mac=active,
we expect to see the MAC address of the new active slave as the source MAC
address after failover. But we see that the source MAC address is the MAC
address of previous active slave.
Emit NETDEV_CHANGEADDR event when bonding changes its MAC address, in order
to let arp_netdev_event flush neighbour cache and route cache.
How to reproduce this bug ?
-----------hostB----------------
hostA ----- switch ---|-- eth0--bond0(192.168.100.2/24)|
(192.168.100.1/24 \--|-- eth1-/ |
--------------------------------
1 on hostB,
modprobe bonding mode=1 miimon=500 fail_over_mac=active downdelay=1000
num_grat_arp=1
ifconfig bond0 192.168.100.2/24 up
ifenslave bond0 eth0
ifenslave bond0 eth1
then eth0 is the active slave, and MAC of bond0 is MAC of eth0.
2 on hostA, ping 192.168.100.2
3 on hostB,
tcpdump -i bond0 -p icmp -XXX
you will see bond0 uses MAC of eth0 as source MAC in icmp reply.
4 on hostB,
ifconfig eth0 down
tcpdump -i bond0 -p icmp -XXX (just keep it running in step 3)
you will see first bond0 uses MAC of eth1 as source MAC in icmp
reply, then it will use MAC of eth0 as source MAC.

and it helped, but the maximum RX speed would still drop to 1 Mbps. As in
the previous fix, the initial gain was determined to be the problem; however,
the problem arises from a setting of the gain when scans are started.

When we have downlink traffic alone and the station is going thru
bgscan, the client is out of operating channel for around 1000ms which
is too long. The mac80211 decides when to switch back to oper channel
based on tx queue, bad latency and listen time. As the station does not
have tx traffic, the bgscan can easily affect downlink throughput. By
reducing the listen time, it helps the associated AP to retain the
downstream rate.
